Axis R rotates, and can be mounted to brake pedal 42 in opposite end part.Motor 94 can be fixed to brake pedal 42,
And it is configured for based on the ignition signal for example from controller 32 come rotating threaded rod 96.Threaded frame 98 is with threaded connection
To bar 96, and thus it is configured for axially moving along bar when bar rotates.Rotation axis R generally can be with rotary shaft
Line 48 and rotation axis 50 interact.It is measurable along rotation axis R and between pivot axis 48 and pivot axis 50
Adjustable distance (referring to arrow 100).
The operation of governor motion 43 can be started using man-machine interface (HMI) 102 by driver.HMI102 can be configured to
For the selection of softer or tighter brake pedal feel to be supplied into driver, and can be to include switch and interactive touch-screen
Any various interfaces.In operation, if driver it is expected tighter brake pedal feel, driver can be with the phases of MHI 102
Interaction, and therefore the exportable command signals (referring to arrow 104) of HMI 102 to controller 32.As response, controller 32 can be defeated
Go out enabling signal (referring to arrow 106) to motor 94, this causes motor to rotate in a first direction, and this moves frame 98 far
From pivot axis 48, thus add distance 100.By increasing distance 100, the tightness of brake pedal feel is increased, and is made
Dynamic pedal travel can reduce.Similarly, if driver it is expected softer brake pedal feel, driver can be with the phases of MHI 102
Interaction, and therefore the exportable command signals 108 of HMI 102 to controller 32.As response, 32 exportable enabling signal of controller
(referring to arrow 110) to motor 94, this causes motor to rotate in a second opposite direction, and frame 98 is moved towards pivot by this
Shaft axis 48, thus reduce distance 100.By reducing distance 100, the tightness of brake pedal feel is lowered, and braking is stepped on
Plate stroke can increase.
